. FUEL-EooINoMIz ER Application filed Aiigus't 2, 1913. Serial No. 782567.

To all L071 0mit'may. concern Be it known that I, WALTER, Bnrmnrr, a citizen of the United States,--residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful I m'provements in F uel-Economizers, of which thefollowing is a specification.

Thisiirvention relates to new and .useful' improi 'ements ina fuel economizerl.

The object of the invention is to provide a device of the character described whereby the l'lnoonsumed carbon and gases given off from the ordinarystove or oven or other consuming furnace may be 'reconveyed to the combustion chamber and utilized.

It is a well known fact-that'in the con} sumption of such fuels as coal, from seventyfive to ninety per centL-of the fuel passes'oif iii. theform of unconsum'ed gasand Smoke and ordinarily is wasted.

It. is the object of this invention to reconyert this, gas and smoke .into combustible form-and reconvey it' into the furnace chamher where it is completelyconsumed, thus completely utilizing allof the fuel.- I a With the above and other objects'in view",

the invention-has particular relationto cer- '"tain novel features of construction, and arstove in which coal orfother fuel consumed in the usual manner, said store liar-- ing the removable ashpan 1 in the lower portion thereof to receive the final products of combustion. From this store leads the pipe 2 which coinnmnicates witha-coiled pipe which is surrounded by and inclosed' in the tank 4 which is at all times kept full' ofpuld water. The smoke and gasesgiren oti' from the lmrning fueliin the stove 1 passes through the pipe 2 and the coil 3 and is cooled .in said c'oil and passes therefrom through the pipe 5 which communicates with andleads from said coil *3. created through these pipes and coil by meansof the suction fan 6 which is driven Suction by the motor the object of cooling. the, gases by pass ngthem through the coil 3 is to prevent the excessive heating and -possible melting offthe fan 6. 'fThe' pipe 5 ex- .tends down into" a Water tank 8 which-is filled. practically fullof water sons to immerse'the lower 'free'fend of.tl1e' pipe/5.. A tank 9 is provided which is partly filled wlth. Water and kerosene or other similar o1l 1s then poured into said tank upon said water untilthe tank is almost filled.

Specification of Letters Patent. P t ts '11 e 21 1915" Leading from the tank 8 is a pipe 10' i which extends downinto the .tank 9 and whose lower end is immersed in the water therein-and leading from the tank 9 is a p pe: 11 which extends intothe combustion ichambero f the stove or furnace. The .end

of said pipe ezrtending into said sto-ve has-a nozzle-12 haylng a pluralityof-discharge :orifice through Which the gas is discharged Into, the furnace where combustion of said gas takes place. his obvious that as-the unconsumed gas passes through the water in. tank 8, it will be filteredand all ashes and cinder.'and other foreign matter will I remain in said water and alsothe possibllity of any fire passing into the tank will be cut off. The fan 6 creates a siifficientidmft for the stove '1 and also forces the gas under pressure'through the. tanks 3' and 9. As the gas passes'from the ,pipe- 10 passes up through the oil in thetank 9 and is enriched therebyand thereby becomes more combustible thus insuring a better flame and more complete combustion.-

By the use of 'this'economizer, a'll smoke is eliminated and fall unconsulnedicarbon which passes from the burningfuel is uti-- lized.

.Vhatl claim is:-

1. In a. fuel economizer,. the combination with a combustion chamber. of a .gas pipr leading therefrom, a cooling chamber throughwhich said 'pipe passesa current.

generator cominunicatingwith the pipe for creating a suction 'therethrough, two other tanks, the former of which is provided to contain water and the latter of which is provided to contain water and'fuel oil. said pipe extending into one of said two tanks and its end being immersed. in the water contained therein. a pipe extending from saidlast menti ned tank and extending down into the other of said two tanks and harin'g'its end immersed in the water theren, a discharge pipeleadingfromsaid last ing from said combustion chamber and extending down into said tank and into the WZItGICOIltHlIlGd therein, a chamber 1n which I a'section of said conduit is coiled provided to contain Water for cooling the gas passing through the conduit, a means for'creating a suction through said conduit, a fuel tank, a fluid conduit leadingjfrom the first men tioned tank and extending down into said fuel tank, a fluid conduit leading from said fuel tank and discharging into the combustion chamber and a discharge nozzle with;

in the combustion chamber carried by the discharge end of the last mentioned fluid conduit. 7

, 3. In a fuel economizer, the combination with a combustion chamber, of a Water containing tank, a fluid conduit leading from said combustion chamber and extending down lnto'said tank and into the water contamed therein, a section ofsaid conduit being coiled and a chamber inclosing said 1 coiled section and provided to contain water for cooling said coil, a suction fan communicating with said conduit and creating a current theretlirough, a fuel '-tank, a fluid conduit leading from the firstmentioned 'tank and extending through into said fuel tank, a fluid conduit leading from said fuel tank and discharging into the combustion chamber, a nozzle carried by the discharge end of said conduit, said nozzle havinga plurality of discharge orifices through which the fuel is discharged into the "combustion chamber. K

In testimony whereof I have signed my name to this specificationin the presence of two subscribing witnesses.
